MOP-WRINGER.

SPECIFICATION forming part of Letters Patent No. 504,077, dated August29, 1893.

Application filed October 10, 1892. send No. 448,396. (No model.)

To all whom it may concern;

Be it known that I, ARTHUR M. BURNHAM, a citizen of Gardiner, in thecounty of Kennebec and State of Maine, have invented certain new anduseful Improvements in Mop-Wringers; and I do hereby declare thefollowing to be a full, clear, and exact description of the Invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in mop wringers,the object beingto produce a mop wringer which shall be simple in construction, easy tooperate and effectual in the performance of its functions.

With this object in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts ashereinafter set forth and pointed out in the claims;

In the accompanying drawings: Figure l is a plan view of myimprovements. Fig. 2 is a sectional view. Fig. 3 is a side view. Fig. 4is a vertical sectional view. Fig. 5 is a view of the mop and holder.

A represents abucket having a contracted mouth A, in which my improvedwringer is located. I

Located in proximity to the sides of the bucket, within the mouth A, aretwo plates at, a'placed parallel with each other andsup: ported by meansof brackets b. These plates,

together with a slotted or perforated bottom. plate-c constitute a framein which squeezing jaws D are adapted to operate as presently explained.The plates at, a are connected together at or near their upper edges byrods or bars (1, said bars serving to rigidly connect the plates (1 andalso to prevent the escape of the clamping or squeezing jaws.

A frame or yoke O is located beneath' the bottom plate 0 and is providedwith ears or arms 2, to which the lower ends of squeezing jaws D arepivotally connected, said jaws ex.- tending upwardly within the frameformed by the plates a. The jaws D are preferably curved inwardly towardeach other at their upper ends and are slotted or perforated for theescape of water from, the mop which is inserted between them. They arealso preferably provided with strengthening ribs f. The upper end ofeach jaw D is made with a recess 9 for the accommodation of the mopholder, and at each side of the recess g in each jaw, slots h are madefor the reception of lugs or hooks h, projecting from a plate or crossbar h? of. the mop holder.

f In making the mop holder a yoke 01 is employed, having its endsconnected with ears 7; projecting from an internally screwthreaded nutiThrough this nut ashank '6 havinga screwthreaded portion 2' passes.Ahandle 2' issecured to the upper end of the shank while its lower endpasses through a perforated boss '0' projecting from the plate or crossbar la the forward end of said shank being preferably pointed orcontracted to enter the mop which is placed between said plate or crossbar and the yoke i. When the mop is placed between the jaws D, thelatter will be closed and the lugs or hooks h will be made to engage theslots h in the upper ends of the jaws and maintain the jaws closed withthe mop between them. Should the jaws now be forced. downwardly thewater contained in the mop will be squeezed out by being forced downagainst the bottom plate 0 by the curved topsof the jaws D. The bottomplate 0 will besecured at its ends to the plates a, a and at a pointbetween its ends has a post or standard j secured to it, the lower endof said post or standard being secured to a bracket j in the bottom ofthe bucket. A spring E encircles the post or standard j, hearing at oneend against the yoke or frame 0 and at its other end on the bracket j.By the employment of this spring the jaws will be returned to theirnormal position when pressure is removed therefrom.

Brackets 7c are secured to the sides of the plates a, a, and otherbrackets is are secured to the sides of the bucket Ain alignment withthe brackets 7c. Mounted in these brackets and passing through the sidesof the bucket are short shafts Z, one at each side of the bucket. Toeach shaft Zbetween the plates a and the sidesof the bucket, a bar m isadjustably se- ICO the lower ends of the jaws D, or from the journals ofsaid jaws. From the outer ends of the shafts 1 arms 0 project upwardlyand slightly forwardly and attheir upper ends have the ends of a yoke Fpivotally connected to them, said yoke extending around and below themouth A of the bucket and midway between its ends is provided with afootpiece 1" and thus constitutes a treadle.

In operating the device the mop will be placed between the jaws D andthe foot piece pressed,whereupon the jaws will be closed through themedium of the rods 01. and arms 12. and the lugs or hooks 71/ made toengage the slots h. The operator will continue to press upon the footpiece '1', whereupon the jaws D with the mop between them, will beforced down wardly,the mop being compressed between thecurved upper endsof thejaws and the bottom plate 0 and the water in the mop permitted toescape through the perforated jaws D and bottom plate 0. The closing ofthe jaws after the mop shall have been placed between them will, asabove explained, he automatic.

The device is very simple and efficient in the performance of itsfunctions.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a mop wringer, thecombination with a frame, of two jaws adapted toreceive a mop between them, and means for operating said jaws tocompress the mop between their free ends and the bottom of the frame,substantially as set forth.

2. In a mop wringer, the combination with a frame having a bottomprovided with open ings, of pivotally supported jaws having openingstherein and adapted to receive a mop between them, of means forcompressing a mop between said jaws and the bottom of the frame,substantially as set forth.

3. In a mop wringer, the combination with a frame, of a yoke arrangedbeneath the bottom of said frame, jaws pivotally connected to said yokeand adapted to receive and in close a mop, and means for compressing themop between said jaws and the bottom of the frame, substantially as setforth.

4. In a mop wringer, the combination with a frame, of a yoke arrangedbeneath the bottom thereof, jaws pivotally connected to said them, meansfor forcing said yoke and jaws downwardly to compress the mop betweenthem and the bottom of the frame, and a spring beneath said yoke forreturning it and the jaws to their normal positions, substantially asset forth.

6. In a mop wringer, the combinationwith a frame, of two pivoted jawshaving slots in their upper ends, and a mop holder having lugs or booksadapted to enter said slots and retain the jaws closed with the mopbetween them, substantially as set forth.

7. In a mop wringer, the combination with a frame comprising twoparallel plates and a bottom plate secured at its ends to the parallelplates, of a yoke located beneath the bot tom plate, jaws pivotallyconnected to said yoke and adapted to receive a mop between them andmeans for operating said jaws to compress a mop between them and thebottom plate, substantially as set forth.

8. In a mop wringer, the combination with a frame comprising two sideplates and a bottom plate secured at its ends to the side plates,brackets for securing the side plates to the bucket in which the deviceis located, and a post or standard extending fromthe bottom plate to thebottom of the-bucket, of a yoke located beneath the bottom plate aspring for normally maintaining the yoke in its elevated position, jawspivotally connected to the yoke and means for depressing the yokewhereby the mop will be compressed between the jaws and the bottomplate, substantially as set forth.

t 9. In a mop wringer, the combination with a frame, of a verticallymovable yoke, jaws pivotally connected to said yoke and adapted. toreceive a'mop between them, arms porjecting from said jaws, a shaft ateach side of said frame, bars attached to said shafts, links or rodsconnecting said bars with the arms of the jaws, arms projecting from theends of said shafts, and a foot treadle attached to said arms,substantially as set forth.

10. In a mop wringer, the combination with a frame, of a verticallymovable yoke, jaws pivotally connected to said yoke and adapted toreceive a mop between them,-arms projecting from said jaws, a shaft ateach side of said frame, bars adjnstably attached to said shafts, linksor rods adj ustably connected to said bars and pivotal] y connected tothe arms of the jaws, arms projecting from the ends of the shafts, and afoot treadle attached to said arms, substantially as set forth.

' 11. In a mop wringer, the combination with a frame, of hinged jaws,means for closing said jaws, and means for operating said jawsto-compress a mop between them and the bottom of the frame,substantially as set forth.
